This seems to work at boosting my kitties immune systems. I recently took it with me when we evacuated from hurricane Irma. My cats tend to get sick from stress but we didn't have any of my 5 cats get sick while gone for 5 days even though they were super stressed out. They like the taste too. My cats are picky and usually if they see I added something to their can food they won't eat it, but they seem to like this and will eat their food right up with this in it. Good product.

This has helped by sick cat for the last 8-10 years. He has herpes and gets symptoms (red inflamed gums and his eyes tear terribly) that only this has helped His litter mate was taking supplements prescribed by a vet for the same problem and passed away 5 years ago. Great product! I will keep using it!! I found that if I missed a few days his gums would start getting red and he would get black tear stains around his eyes. Had to make it part of his routine everyday

My cat likes the taste. I mix it with canned food. His herpes infection has become much smaller after 3 weeks of treatment.

Cats seem to like it sprinkled on food

We are Whisker Kisses Koalition, a 501 (c) 3 non profit animal rescue providing rescue, rehabilitation and safe haven to abused, abandoned, injured and confiscated cats, exotic pets and farm animals with medical, physical or behavioral conditions providing a life home. We purchased to boost immunity for our permanent cat residents. Cats liked. Would eat food in which it was mixed.

Cats love it, so I love it & it's less expensive than what I had been using.

My vet recommends giving our cats L-Lysine every day. This has helped their immune systems after numerous respiratory and eye infections.

I wish I had not bought this product and will not purchase it again. I did not realize that the L-Lysine is only 250mg per scoop and the scoop is much bigger than the other brand I had been using. Also, and most importantly my cats would not touch their food tonight! I feed only high-quality cat food that runs about $3/can and I have 7 (crazy cat lady!), cats to care for so that says a lot when not even one cat would eat their food with this added. I did notice a strong smell when I opened the jar but I figured it would be appealing to them but boy was I wrong!I gave one star b/c my cats do not like the flavor, because there was no clear indication that the product contains Beet SUGAR and so if my cats did like the flavor I could not give it to my DIABETIC kitty, and because the product is the same price as the one I had been buying but contains half of the supplement. But, what is most upsetting is that I did not know the product contains sugar before I made the purchase. I really hope to be able to return this product.

Well I don't love it...but the cat sure seems to. Night and day difference for a cat who (not uncommonly we read) has some sort of feline herpes. We HAD been paying a large amount to a vet for steroid/antibiotics for a cat with a frequent inflamed eye. Not sure who told my wife about an also-vet-expensive liquid form of this. I don't think the cat has had an issue for 2-3 YEARS now, and she used to have it almost MONTHLY. Good price, works, cat likes it with her wet food. I am NOT some believer in "alternative medicine" or any such thing, but was VERY pleasantly surprised that this stuff make a huge difference to a sweet cat (who is no longer frequently miserable).

I have several cats and it helps them stay healthy....vet recomended

Long-lasting immunosupport for cats. Simply mix a few scoops into wet food or sprinkle on dry. Helps with upper respiratory issues and as a general maintenance supplement. I use this with feral cats, and they always eat the food it's mixed into.

I went through 3 different types of treats before I found this powder. My cats are super picky and would just play with the treats instead of eating them. This powder is easily disguised in food, and my cats eat it up. Their eye issues have cleared up and their overall health has improved!!

GREAT PRODUCT! Lonoke County Animal Education and Rescue Team is a local rescue group in Lonoke County Arkansas.... We put this on all our Cats and Kittens food and it works GREAT!! Helps aid in their respiratory health as a means of prevention of any respiratory issues that may arise housing numerous cats and kittens together! It improves their overall health and makes their fur just as soft and shiny! We love it!! Thank you!!

Does the job in supporting the immune system

My cats love this (all 6 of them!) they eat it as a treat straight from the jar. I also sprinkle it on their dry food.

great price

I have been using this product for a couple of months. Two of my cats have feline herpes symptoms and although this amino acid doesn't cure, it certainly reduces symptom severity. I've seen less coughing, sneezing, and runny/watery eyes. I can tell the cats feel better. It's your best bet since there is no cure for feline herpes.

great product

I wish I would have looked closer at the dose of each scoop before purchasing....it's only 250 mg as opposed to the 500 mg dose the other brands offer. On top of that, the scoop is larger than the normal brand I use. I won't waste my money on this again.That said, it is ground very finely, and the cats don't seem to mind it.

My cats love this. I had no problem introducing this into their diet. They seemed to enjoy their food even more. I will buy this again.

Cat loves it mixed with a bit of wet food and has controlled symptoms well.

good product

I run a rescue and we bought this for a cat that has a immune system challenge. Thanks!

works great for our kitty's ocular herpes! Keeps outbreaks almost completely under control.

My cat will eat this in wet food. It's too hard to tell if it is making a difference. But, it is one of those,'can't hurt' - 'hopefully, it does help' choices we make.

Good product

This a very easy to use product for cats. Dissolves quickly. No taste.

I will begin by saying this is NOT going to give you instant results. I use this product for two cats but purchased specifically to treat one of the cats with stomatitis. Here is a little history:The cat with stomatitis has swollen gums, plaque build up, bad breath and will not eat anything but wet food. He has been to a vet who recommended teeth extraction (for thousands of dollars). I decided to see if this Felisyl product in combination with Proden PlaqueOff Dental Care for Dogs and Cats would help. Neither of my cats seem to notice any difference in flavour when both products are added to their wet food each day.*After approx. 3 months of use for cat with Stomatitis:**Plaque has been reduced (while not completely gone)***Swelling seems to be under control (while not completely gone)****Bad breath is no better or worse****My cat is eating solid food now which is a HUGE improvement!! I now am able to feed him dental treats and regular food in addition to the wet food with Felisyl and Plaque off added.I will be continuing my use of this product until my cats next vet appointment (July 2016). At that point, I will add to my review as to whether or not his health has improved enough that extraction is not a necessary step.

Well...

Half the cost of buying this from a veterinarian. I recommend always buying this item online. My pets thank you.

Will purchase again

Cat would not touch it no matter what I put it in.

Great product ! Keeps our stray kitty healthy & we simply add it to his wet food.

got a kitty with chronic health issues, I think this helps and she loves to eat it

Excellent product, my cats like the taste and it takes care of their sneezing just like the more expensive brand I was using.

This does absolutely nothing for my herpes cat.

Buyer beware - this is not Viralys. It claims to have the same ingredients and concentration of lysine as Viralys. If so, then perhaps someone can explain why my two cats experienced renewed herpes symptoms within 6 hours upon eating this powder mixed in their food? Why one of my cats, with NO health issues before eating Felisyl, began vomiting after each meal? And why, upon stopping THIS powder, and beginning (more expensive but twice as effective Viralys) their cold symptoms stopped, and so did the vomiting. If you're looking for a cheaper alternative to Viralys, this is NOT it.

Very palatable - My cat, who is being treated w/ antibiotics for an upper respiratory infection associated with Feline Calicivirus (FCV) is rapidly improving. He eats it readily in his feed twice a day.I'm also feeding it to my other, healthy cats to boost their immune systems - they were inadvertently exposed to FCV before I was able to get my newest cat (he was a stray) vetted. Every one of them finds it tasty.An excellent product that lives up to it's billing.

We raise Sphynx (prone to colds). Since starting them on L-Lysine occurrences have drastically diminished. They all take the powder without issue. It has measure spoon included & lasts quite awhile, so a great deal for the price-even in our multi-cat household. Would recommend to everyone.

SEEMS TO ACTUALLY BOOST THEIR IMMUNE SYSTEM SO FAR
